Simple Mosin Nagant Trigger Job

[Krippp]

This is basically a pictorial of a fluff and buff to help with a little of the trigger pull and to ensure a good clean break on the Mosin Nagant family of rifles.  This is applicable to all Russian variations and most other countries as well.  There are some Finnish models that have a different style of trigger and these techniques will not apply to those models.

We will start off with my very first Mosin, a 1944 M44 Carbine.

You will need to take the gun completely apart, there are many resources on the net that teach this and I will not cover that in this one.  We will start with the barreled action removed and take it from there.

First step is to remove the sear screw, then remove the trigger pin by simply sliding it out from the receiver.  The trigger pin is not hard to slide out, it is very easy to just fall out so be careful when taking the gun apart not to let it fall out and lose it.  The sear also doubles as the trigger spring and after removing the sear screw and the trigger pin, remove the sear and trigger together.






The next step is to identify the areas in which you will be polishing, the first is the top of the sear that contacts the cocking piece of the bolt, then you will be polishing the top of the trigger and this area has 2 faces on the same rise, a slanted face and a small flat face at the very top.




Use a fine grit finger nail polishing board like the ones readily available at walmart to achieve the results you want.  Remember, we are not taking off metal, just polishing surfaces and edges.  Use the emery board to polish the face of the sear, the top of the trigger and the front of the T face on the cocking piece from the bolt, and yes you will need to disassemble the bolt in order to do this part.  Keep the board flat and level with the existing surfaces and only polish until there are no overhanging bits of metal and the surfaces are smooth and shiny.  Then proceed to clean the parts that have been polished and apply a good gun oil and reassemble the gun.  Dry fire a few times and you should notice a marked improvement on how the trigger breaks.

Keep the process coming, Krippp. I'm whitetail hunting with my 1944 M44 in two weeks!

It is now finished, any questions or comments?  Please feel free to post them, I hope this helps and hopefully we can get an entire milsurp gunsmithing section going here.

i'd have to try that although i have to say, i have seen worst trigger than mosins. Mine (91/30) and my pastor's M38 actually breaks pretty nice, not target nice but enough to stay on target.

[wickedwd5000]

im pretty lucky with my 91/30 also....of course its the only one ive ever fired, LOL

To add a little, I also like to polish the trigger, sear, and pin down to a 2000 grit.  This will also help to smooth out the trigger.

Also, I have never done this, so I don't know how much to cut, but do have one rifle with the FP spring cut.  With the other trigger work done, it has a very light, and smooth trigger.  I would recommend caution with this though.  You could easily end up with an unsafe trigger, or with light strikes.

I now have another project.... thanks krippp, that is some awesome detail in the instructions. My 91/30 is ettin the treatment now! Ive already done my .17hmr and I think Im down to about a pound on it, love a light trigger!

Thanks for the tips on how to smooth out the trigger pull. While I dont mind the one on my 91/30, my friend does NOT like the pull on his M38.

I got rather lucky when I bought my 91/30. Its a marked Ex-Sniper that I handpicked from a large batch.  My friend with his M38 though did not. Its about 4 different rifles combined into 1 Nagant and did not function properly until I stripped all the cosmoline off it and adjusted the front sight (He'd "adjusted" it as per a you tube video and it was off by about an inch at 100 yards. He'd also shot it with the cosmoline still in the chamber and had a lot of stuck bolt syndrome)

I love my M38's trigger pull, it breaks pretty well and suprises me.

My shots are still all over the place...
